How to add reviews to Wix
The short answer
Build a widget, copy one line of code, and paste it into an HTML iframe / Embed a widget element. Add → Embed Code → Embed HTML. No developer and no theme files.
Step by step
Build the widget and connect your review sources
Choose a layout and match the colours to your site
Copy the embed code
In Wix: Add → Embed Code → Embed HTML
Add an HTML iframe / Embed a widget element and paste the code
Save and check the live page
Where to put them
Dragged in as an Embed HTML element anywhere on the page, or through Settings → Custom Code for a floating badge across the site.
Full-width sections suit carousel and grid layouts; narrow columns suit a badge.
Does Wix have reviews built in?
No. Wix has no built-in review system, so reviews come from an embed or a third-party tool.
If your reviews already live on Google or a marketplace, nothing built into a site builder will reach them.
If they do not appear
Wix wraps embeds in a fixed-size iframe, so a widget can end up cropped. Drag the element taller rather than changing the widget.
